Naturally Smart announced Hen2Home Technology, where the consumer can trace the freshness of the eggs.

An organic laser is used to print the use by date, which is ink and chemical free. The use by date says how fresh the eggs are, and a trace code allows the user to trace the egg back to the farm and confirm the egg production method. It can also tell whether the farm packed the eggs directly from their own hens or received them from a secondary egg producer, if the laying hens were vaccinated against Salmonella or if the hens breed.
